A “critically endangered” species has experienced a loss in population of 80% or more over the past 10 years or the past three generations, whichever time period is longer. “Critically endangered” can also mean an 80% population reduction that is expected to take place in the next 10 years (or next three generations). A species can also be labeled “critically endangered” if it has become extremely fragmented (living in scattered locations or even a single location). Other criteria that is used when listing a species as critically endangered includes:
- A population of less than 250 mature individuals with an expected continuing decline of 25% over the next three years (or one generation), and severely fragmented or living in a single location.
- A population of less than 50 mature individuals
- There is a 50% change of extinction within the next 10 years or three generations.
A species is listed as “endangered” when there is a high risk of extinction with a population reduction of at least 50% over the next 10 years or three generations, the species’ population is severely fragmented and can only be found in no more than 5 locations. Other criteria can include:
- The population has less than 2500 mature individuals with an expected decline of 20% within 5 years or two generations, the population is fragmented or the species only lives in one location.
- There are less than 250 mature individuals
- There is a 20% chance of extinction within 25 years or five generations.
